NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat-jsp-2_3-api package and not the tomcat-jsp-2_3-api package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

An h2c direct connection to Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M5 to 9.0.36 and 8.5.1 to 8.5.56 did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service.
